气缸套是柴油机的主要机件之一。气缸套的内表面直接受到高温高压燃气的反复作用;外表面受到冷却水的冲刷和冷却,使气缸套承受巨大的机械应力和热应力。气缸套又是往复运动组件的导向面,承受了气缸盖传来的密封压力和活塞运动的侧压力作用,使气缸套内表面受到了强烈的摩擦,致使内表 Cylinder liner is one of the main components of diesel engine. Cylinder liner directly on the inner surface of the high temperature and pressure gas repeatedly; the outer surface of the cooling water erosion and cooling, so that the cylinder liner to withstand huge mechanical and thermal stress. Cylinder liner is reciprocating components of the guide surface, bearing pressure from the cylinder head pressure and the piston side of the pressure action, so that the inner surface of the cylinder liner has been a strong friction, causing the inner surface
